DRAINING DEVICE.

Application filed November This invention relates to draining devices particularly adapted for use after a sur ical operation in dralnlng bladders and similar sacs, the present invention being an improvement upon the invention shown and described in another application of mine filed April 27, 1925, and numbered 26,05 1.

The object of the invention is the production of an inflatabletube which is complete in itself and may be mounted upon a catheter of any size and then inflated after it has been inserted into the incision, thereby causing the outer wall of the tube to be forced into contact with the wall of the incision for the entire length of said incision and also into contact with the walls of the perforated member which are adjacent the opposite ends of the incision.

Another object is to provide means in a device of this character which upon inflation of the device will be forced into such firm contact with the catheter that there can be no movement, relatively to each other, of the catheter and the inflatable device mounted thereon.

' These objects are attained by the device illustrated in the accompanying drawings.

For the purpose of illustrating the invention, one preferred form thereof is illustrated in the drawings, this form having been found to give satisfactory and reliable results, although it is to be understood that the various instrumentalities of which the invention consists can be variously arranged and organized, and the invention is not lim ited to the precise arrangement and organization of these instrumentalities as herein shown and described except as required by the scope of the appended claims.

Of the drawings:

Figure 1 represents a longitudinal section of a device embodying the principles of the present invention, and

Figure 2 represents a longitudinal section of the device inserted into an incision and inflated, the catheter on which it is mounted being shown in elevation.

Similar characters indicate like parts throughout the several figures of the drawings.

In the drawings 10 is a catheter which may be of any usual construction, and on which the device embodying the present invention is adapted to be mounted intermediate its ends.

This device consists of an inflatable tube 11,

the opposite ends of which are reduced in diameter as indicated at 12, these ends surrounding a tubular member 13 extending through the tube 11 and having end portions it turned over the ends 12 of the tube 11 and united hermetically thereto.

When the device is constructed as thus described an annular chamber 15 is formed between the tube 11 and the tubular member 13.

Near one end of the tube 11 is a flanged opening'16, to the flange of which is united a flexible pipe 17, the outer end of which is provided with a check valve 18 of any well known construction. This check valve may have a threaded portion 19 as shown in the drawings to which an ordinary force pump may be connected.

After a surgical operation has been performed and it is desired to drain the bladder or some similar sac, the catheter 10 with the inflatable device thereon is inserted into the incision 20, while the device is deflated. When the catheter has been inserted a sufflcient distance air is forced through the pipe 17 into the chamber 15, thereby causing the walls of said chamber to move in opposite directions.

The inner wall of the chamber 15 is a section of the tubular member 13 and under the pressure of air contained within the chamber 15, this section of the tubular member 13 is forced into gripping contact with the outer wall of the catheter 10 so that any movement of the catheter relatively to the inflatable device is absolutely prevented.

This is true regardless of the diameter of v the catheter.

Obviously, in some cases a catheter ofconsiderable diameter is requlred, and in other cases a catheter of very small diameter is needed, but by making the draining device with the tubular member 13 extending therethrough from end to end, this tubular mem her will grip upon the catheter regardless of its diameter when air has been forced into the chamber 15 to inflate the device.

This is of considerable importance for with the draining device thus constructed it is adapted for use in connection with catheters of every description and size and when once applied there is no opportunity forthe device to become displaced fromthe desired position upon the catheter.

Moreover, when the draining device has been disposed in an incision and inflated there is no chance for the catheter to move endwise therein into a position which would cause discomfort to the patient.

In Fig. 2 there is represented 1n dotted lines a portion of a member of the'body in' which the incision 20 has been made. This member of the body has opposed faces 21 and 252 and when the draining device is. p0- sitioned within the incision 20 and inflated the outer wall of the tube 11. will be forced into firm contact withthe wall of the incisionQO from end to end.

Both the tube 11 and tubular member 13 are made of stretchable material and when the chamber 15 has air forced into the same the portions of the tube 11 at. the opposite ends of the incision will be inflated to a greater extent than the portion of the tube within the incision 20.

This inflation will cause bulb-like portions 23 and 2d of the draining device to be formed at the opposite ends of the incision 20. Parts of the outer surfaces of the bulbshaped portions will bear firmly against the walls2l22 adjacent the opposite ends of the incision 20. I

As there is no chance forthe accidental escape of air from the chamber 15 when the device is inflated, portions of the wall of the tube 11 will remain in firm contact with the wall of the incision 20 from end to end, and also in; contact with portions of the walls 21-22 adjacent the opposite ends ofsaid incision, so that there is no possible leakage through the incision 2O from the sac being drained. Consequently, anyliqui'd passing from the sac must necessarily be discharged through the passage 25 in the catheter 10.

Heretofore, after surgical operations where it is necessary to artificially drain the bladder, sac or canal by means of a catheter or similar tubularmembery it'has been necessary to cover the body of the patient with sponges made of absorbent gauze to care for all discharged matter not passing through the bore of the catheter.

It has heretofore been impossible to confine the'discharge of this matter through the bore of the catheter and there has always been considerable leakage through the incision itself which causes the patient much discomfort.

With 'applicants invention all of these objections are entirely overcome and the patient is kept perfectly clean and free from all moisture due to leakage of the contents of the particular sac being drained.

It is believed that the operation and many advantages of the invention will be understood without further description.

Having thus described my invention, I claim:

1.- A new article of manufacture adapted tobe mounted upon a catheter and consistingof an inflatable device having both its of through which air may be forced into the space between said tube and tubular member.

3. An inflatable tube having a tubular member therein and secured to the opposite ends thereof, said tubular member being adapted to be mounted upon a catheter to close an incision in which the catheteris disposed while draining a sac; a flexible pipe secured to said tube near one end thereof throughwhich air may be forced into the space between said tube and tubular member; and a check valve at the outer end of said pipe.

' A draining device formed of stretchable lal with an annular chamber therein and adapted to be mounted upon a'catheter to close an incision in which the catheter is disposed while draining a sac; and means whereby air may be admitted under pressure to said chamber thereby causing the outer and inner walls thereof to be forced in opposite directions with the innerwall in gripping contactwith the'catheter and the outer wall in contact with the wall of said incision.

5. The combination of a catheter for draining a sac through an incision; a device mounted thereon formed of stretchablemate ial and having an annular chamber therein; and meansfor forcing air into said cham ber to cause the outer wall of'said chamber to be forced into firm contact with the entire wall of said incision and the inner wall into gripping contact with the ca heter.

6. The combination of'a catheter for draining a sac through an incision; a device mounted thereonformed of stretchable material and having an annular chamber there in; and means for forcing air into said chamber to cause the outer wall of'said chamber to be forced into firm contact with the entire wall of said incision and the inner wall into gripping contact with the catheter. said. device being capable of greater inflation at'the opposite ends of said incision causing portions of said outer wall. to firmly contact with the opposite faces of the perforated part of the body atpoints adjacentthe ends of said incision.
